Fatal Trouble

Summary:

No-one could fault you for jumping at the first chance to kiss your best friend, the man you had a crush on for years, Gojo Satoru. But had you been a bit more observant, you might have noticed that it wasn't Satoru you were kissing, but his shy, quiet twin-brother.

Work Text:

The air in the bedroom was still, thick with the scent of old paper and the faint, sweet dust of spilled Oreos. You didn’t notice. All you could taste was mint and heat and the shocking softness of Gojo Satoru's mouth, yielding under yours with a startled, desperate sound.

It wasn't a groan so much as a fracture, a sharp and stifled "Hngh " that vibrated against your lips before dissolving into a wet, open-mouthed gasp as you licked inside. Your thumb found his lower lip, plush and damp, and pressed down. He shuddered.

"Oh, god," Gojo moaned, his words muffled, breathless. A warm hand hovered, trembling in the air beside your hip, before settling on your waist, fingers digging in through the fabric of your shirt, "You want this? You actually want me?"

You leaned into the delicious touch, rolling your hips forward. The hard line of his erection strained against his pants, a blatant, thrilling pressure against your thigh. You ground down, earning a choked-off whimper that went straight to your core.

"More than anything," you breathed, and it was the truth. You'd wanted Satoru for years. Through countless afternoons in his perpetually messy room, your legs swinging off the edge of his unmade bed while he flexed a bicep, and demanded you acknowledge its growth.

You knew the landscape of his chaos by heart. The Red Bull racing jacket slung over the second-hand couch, the galaxy of LED strips on the ceiling, the expensive whiskey stolen from his father's office, hidden under the bed next to a box of daifuku. You knew the sound of his voice, loud and bright and endlessly boasting.

You knew the flush that painted Gojo's cheeks when he laughed, the predatory glint that twinkled in his blue eyes when he was focused on scoring a goal.

You knew all of that. So you didn't question the clean, woodfire-like scent that wasn't his usual overpriced cologne. You didn't register the absence of a thumping bass from a portable Bluetooth speaker, overpowering the raging party downstairs. You didn't wonder about the lack of a jersey-strewn floor.

Your mind was full of Satoru, the fantasy of him. Finally you had him, lips parted and moaning against you.

His kiss was hungry, but there was a clumsiness to it, a frantic and untutored edge that you assumed your best friend would lack. Teeth clacked against yours, and the hand on your waist slid around the small of your back, pulling you flush against him with a strength that made you gasp.

Gojo took advantage of that, his tongue surging forward to meet yours, not with the practiced and teasing swagger you may have anticipated, but the raw and consuming intensity that felt like being devoured.

You broke for air, panting as you rested your forehead against his feverish skin. Your eyes began to blearily crack, swimming with sensation. It was only then that other details began to bleed through.

The bed behind Gojo's knees was firm, the comforter taut and neatly tucked. Not the familiar and chaotic nest that you were accustomed to. the light was different, a warm and steady glow from a desk lamp, not the pulsating ice-blue sparkle of LEDs. And the sounds were reduced to the quiet hum of a laptop fan, and the ragged symphony of your breathing mingled with his.

Your eyes sharpen in the dim gloom, landing on the Star Wars poster first. The Empire Strikes Back. Centred perfectly on the wall opposite the bed. And then the desk, obsessively ordered with a closed MacBook aligned precisely with a stack of textbooks. Thick volumes, like An Introduction to Quantum Field Theory, The Mathematics of General Relativity.

Behind them, a humble pile of manga, a volume of Shingeki no Kyojin dog-eared open to a tense, detailed art of two brothers, Eren and Zeke Yeager facing off against one another. Your gaze drops, a porcelain plate in a delicate robin's egg blue, upon the desk. On it, a half-open packet of Oreos had spilled a constellation of black crumbs across the surface.

Oh, the glasses. You hadn't felt them during the kiss, hadn't thought about them while his mouth slanted over yours. But you see them now, slightly askew on the bridge of his nose, thick and black-framed lenses that magnified the most startling, familiar shade of blue.

A jewel-blue currently wide with shock, and a hunger so deep it looked like terror.

This wasn't Satoru.

Satoru's nose has always been straight, proud. This one had a slight, scholarly bump on the bridge. Satoru's hair was a wild and artful mess of white, ruffled by his own hand and often stuck beneath a plain, crooked cap. This was cut neater, softer at the temples. Satoru filled any room with his presence, but the Gojo in front of you seemed to absorb the silence around him, to live within it.

Gojo Satoshi.

The quieter of the two twins. The genius. The ghost who inhabited Satoru's loud and glorious shadow. You'd seen him in passing for years, a figure in Uniqlo cable-knit sweaters and pressed chinos, always lugging around a humble stack of books, his voice a low rumble that you'd maybe heard a dozen times total.

Satoru often mentioned him with a soft of affectionate, bewildered pride. My brother's rewriting spacetime in the library. Boring, isn't it?

You had kissed Satoru's 'boring' brother. And he had kissed you back like a man who had been starving for a lifetime. And judging by the low heat pooling in your gut, the slick that you knew seeped through your lace panties, he had incited a fire in you that was anything but dull.

His hand was still on your back, a brand through your shirt. His other had come up, fingers tangling hesitantly in the hair at your nape. He was breathing as if he had run a marathon, his chest heaving against yours. The hard length of his arousal pressed insistently upon you, and it hadn't softened for a second.

If anything, it felt more pronounced. A rigid and righteous truth between yo.

"You're not, oh– " You started, voice a hoarse whisper, "You're not Satoru."

He flinched as if he had been struck. The hungry light in his eyes flickered, dimming into something horrified, wounded and ashamed. His warm grip loosened, beginning to pull away, "I'm sorry. I thought...I thought you knew. I thought you meant to– "

He was going to apologise. He was going to stop.

And something primal in you rebelled. The heat was still there, coiled dormant in your belly. The taste of him, of mint and Oreos and something uniquely, intellectually sharp, was still on your tongue. The evidence of his want was a solid, thrilling weight against you. And the shame in his eyes was somehow hotter than Satoru's confidence had ever been.

Your hand, which had fallen from his soft lips, shot up. You didn't push Satoshi away. You fisted your hand in the soft, expensive wool of his sweater, right over his pounding heart.

"Yeah, I didn't know," you said, the words falling from your mouth in a rush. You watched his face twisted, as though he was already prepared for the condemning fury that would drive you away from him forever, his breath hitched.

"But I don't want you to stop."

The change was instantaneous, the wounded look shattered, replaced by a flush so intense that it stole the air from your lungs. You remembered Satoru's words about his twin brother. The shy one out of the two of us. He's quiet, doesn't really get around much. He never even goes on dates either.

The hand at your back clamped down, yanking you against him with a force that made you yelp. His mouth crashed back onto yours, no hesitation left.

This kiss was different. It was claiming, and it was filthy, pornographic in its force and sound.

A low, guttural sound ripped from his throat, "Mmph, fuck!" as he walked you backwards. The back of your knees hitting the edge of his perfectly made bed. You tumbled onto it, him following you down, his body covering yours, all lean muscle and toned definition unleashed. The neat comforter wrinkled violently beneath you.

He broke the kiss to trail his mouth down your jaw, your neck, his teeth scraping over your pulse point. "You feel it?" he growled against your skin, his voice deeper, rougher than you’d ever heard it. He rocked his hips, grinding that relentless hardness against the seam of your jeans. "Feel what you do to me? I've watched you. For years. In his room. Laughing. God, I've wanted you so bad."

His blatant, blurted confession was a lit match dropped in gasoline. You arched up, meeting his thrust, a broken moan escaping you, "Satoshi– "

Hearing his name on your lips seemed to undo him completely. He reared back, just enough to look down at you, his glasses slightly fogged, his snowy hair disheveled. His hands went to the hem of your shirt, "Off. Now. Please."

It wasn't a request nor a demand. It was a fervent, desperate prayer. The cool air of the room hit your bare skin, raising goosebumps. Satoshi didn't give you a second to feel exposed. His gaze, magnified and blazing behind his glasses, drank you in, not with shyness, but with a voracious, focused intensity that made your breath catch. This wasn't the tentative boy from the hallway. This was a man who knew exactly what he wanted.

"God, you're perfect," he murmured, the words a rough scrape of sound. His hands, which you’d always seen holding pens or turning textbook pages, settled on your ribs. They were warm, slightly calloused, and they spanned your waist with an easy possessiveness before sliding up to cup the soft weight of your breasts.

A shocked and sharp gasp left you as his thumbs brushed over your nipples, already tight and pebbled. He watched your face, cataloging every twitch, every flutter of your eyelids.

"So sensitive, responsive," he noted, a hint of that academic curiosity colouring his tone, now turned utterly carnal and ragged, "Let's see, hmm?"

Satoshi bent his head, white hair falling over his forehead, and his mouth was on your nipple, not tentative, not exploratory, but knowing. His lips closed around one peak, his tongue laving it in a firm, wet circle before he sucked, deep and deliberate.

"Ah! Satoshi!" Your back arched off the bed, a jolt of pure, white-hot pleasure spearing straight to your core. Your hands flew to his hair, tangling in the soft white strands, holding him to you. He groaned against your skin, the vibration making you cry out again.

He switched sides, giving the same devastating attention to your other breast, biting down just enough on the stiffened peak to make you jerk and whimper, "You like that?" he asked, his voice muffled against your flesh, and he didn’t wait for an answer, "You do, huh? I can feel you shaking."

Satoshi released your nipple with a wet pop! and looked up, his lips slick, his glasses slightly askew. The dominance in his expression was staggering, "Spread your legs wider."

It wasn't a question. It was a soft, and firm command. Heat flooded you, a liquid pulse between your thighs. You obeyed, letting your knees fall open, and he immediately settled into the space he demanded, the rough fabric of his pants a maddening friction against the sensitive skin of your inner thighs.

The hard ridge of his cock pressed insistently against your clothed cunt, and your rocked up against it, seeking sweet relief.

"Tsk, impatient," Satoshi chided, but his eyes darkened with approval, as he leaned down again, capturing your mouth in a searing kiss as one hand continued to knead and palm your breast, his thumb rubbing relentless circles over your taut nipple. The other hand slid down your stomach, fingers dipping beneath the waistband of your jeans, teasing, "So hot for me already. And you thought I'd be shy? That I wouldn't know how to fuck you right, how to fuck you as you deserve?"

"I — I didn't know," you panted, breaking the kiss to gasp for air, "Satoru always said you were– "

"Gonna' talk about my brother when I'm the one sucking your tits?" There's a hint of a smile colouring Satoshi's voice, as he ducks his head back to your chest, sucking a bruise mark just above your glistening areola, "Fuck, baby, you taste incredible. I could this for hours, just feast on you. Would you let me? Would you lie here and let me use my mouth on every inch of you?"

The filthy promise in his words coil tight in your abdomen. You were moaning openly now, little punched-out sounds with every pull of his mouth, every skilled roll of his fingers over your aching, wanting flesh. The world had narrowed to the scent of him, your best friend's younger twin, the quieter of the two. All you could think about was the wet, hot suction of his lips, and the building, desperate throb between your own.

"Hey, have you seen my — what the fuck?"

A familiar voice, loud and brimming with shock that echoed in the sudden, frozen silence.

Satoshi went rigid against you, his mouth stilling on your chest. You felt as though your entire body locked, head snapping towards the door.

Gojo Satoru stood in the doorway, a cheap plastic cup dangling from his long fingers. His blue eyes, so like his brother's and yet so fundamentally different, were wide, taking in the scene. You, shirtless and flushed, sprawled across his twin's bed. Satoshi, nestled between your thighs, his face buried in your chest, his hands roaming over bare skin.

The intimate, humid heat of the room seemed to visibly crash into him. For a long, suspended second, no one moved. No one dared to breathe.

Then Satoshi slowly, deliberately lifted his head. He didn't scramble away, didn't fluster and push his skewed glasses back up the bridge of his nose. His expression was a masterpiece of exasperated annoyance painted over a deep, furious flush. A string of saliva connected his lower lip to your damp skin for a second before breaking.

He sighed, a long-suffering, deeply put-upon sound, "Come on, man. Now? Really?"

His tone was so dry, so utterly Satoshi, like the quiet twin you had often brushed past in the corridors, that it broke the paralysis. You jolted, attempting to sit up, to cover yourself, your own face burning with a mixture of shock and mortification, "Satoru, I — we didn't, it's not– "

But Satoru wasn't looking at you with anger. The initial shock was melting away, replaced by something else entirely. His gaze traveled from your face, down your exposed torso where Satoshi's hand still rested possessively, to the obvious and telling flush crawling up his brother's neck, and back to your wide, teary eyes.

A slow and wicked grin spread across his face, the same smile you had seen plastered over his expression after scoring a winning point, after pocketing a pretty girl's number, after making you laugh so hard your ribs hurt.

"Oh, it's not...what? I'd say it's something," Satoru drawled, stepping fully into the room and kicking the door shut behind him with a soft thud! The lock clicked, and the finality of the sound sent a new and entirely different kind of shiver through you.

Satoru tilted the cup back, catching the last remnants, eyes still following the minute shiver that ran through you, the cool air of the room stiffening your bare nipples. Your best friend set the cup down carefully on the edge of his twin's desk, right beside the plate of Oreo crumbs.

He pulled out the desk chair, straddling it backwards, resting his arms on the backrest. Settling in.

"Don't stop on my account, man," Satoru said, his grin turning sharp, predatory in a way that made your thighs clench around his brother's waist.

Satoshi stared at him for another beat. You saw the conflict in his eyes, the embarrassment warring with defiant and a rare flicker of something competitive. Then, with a quiet huff that was almost a laugh, he looked back down at you. His gaze has changed, for the initial shock was gone, burnt away by a new and daring heat. His brother's presence wasn't a deterrent, it was a catalyst.

"You heard him, baby," Satoshi murmured, his voice dropping back to that intimate, commanding rumble meant only for you. His hand, which had stilled, resumed its slow, kneading motion on your chest, as he lowered his head. White hair brushing your neck as his breath ghosted over your tits, "We have an audience."

Without breaking his suction on your sensitive peak, his hands shifted. One arm hooked under your back, the other beneath your knees, and with a startling and effortless strength that belied the image of the silent nerd you had always been presumptuous about, Satoshi flipped you.

The world spun for a dizzying second, as the Star Wars poster blurred, then resolved. Now you were facing the door, facing the desk. And facing Satoru.

Your back was pressed flush against Satoshi's front, his hard length a searing brand against the curve of your ass. His arms came around you, crossing over your bare stomach, holding you securely in place against him.

"Look at him, baby," Satoshi breathed into your ear, his voice thick with his own arousal and a newfound, exhibitionist boldness. His large hands slid up, covering your tits completely, palming and squeezing the soft flesh. He plucked at your nipples, rolling the stiffened, moistened peaks between his thumbs and forefingers, presenting them like an offering, "See? Look at what we've got here, Satoru. God, they're so perfect, aren't they?"

His tone was a mix of reverence and blatant boasting. He was showing off his discovery, his prize, to the only other person in the world whose opinion might matter.

From his chair, Satoru released a sharp and appreciative exhale. His eyes were locked on his twin's hands moulding over your breasts. You watched, mesmerised and mortified and impossibly turned-on, as Satoru's own hand disappeared into the waistband of his low-slung jeans. You could see the deliberate movement of his forearm, the shift of fabric.

"Fuck, yeah, they are," your best friend agreed, his voice worn down to gravel. He wasn't just watching anymore, no. He was participating, for the rhythmic motion of his fist beneath the denim was unmistakable. "Always knew it. Knew you'd be hiding a killer rack beneath those pretty sweaters, sweetheart. Fuckin' spectacular."

Hearing the crude, familiar praise from Satoru's cocky lips, your best friend, the object of a years long crush, while pinned against his brilliant, dominant twin sent a violent shudder through you. A fresh wave of wetness soaked through your already damp underwear, a slick and hot confession Satoshi would undoubtedly feel against his own clothed hard-on.

"She's dripping," Satoshi murmured, his voice smug against your ear, glasses slipping down his hawkish nose. He kissed the junction of your neck and shoulder, teeth delicately bruising the sensitive skin there, "Can you see how pretty she is? All flushed and desperate?"

"I can, fuck — I can see that," Satoru gritted out. His breathing was becoming uneven, matching the pace of his hidden strokes as his hips began to roll at a grinding pace. "Quit teasing, man. Get to the good part, touch her."

Satoshi snickered, "So impatient. Always rushing." But he obeyed, adjusting his grip. His large hands slid from your breasts, down the quivering plane of your stomach, leaving trails of fire. They hooked into the lace band of your panties.

"Lift your hips, baby," he commanded softly. You did, a helpless puppet to his will. He drew the scrap of fabric down, slowly, torturously, over the plump swell of your mound, past the neat thatch of hair. The cool air hit your exposed folds, making you gasp. He didn't remove them completely, just tugged them down to mid-thigh, leaving you obscenely open.

Then, with a clinical precision that was devastatingly erotic, Satoshi used his thumbs. He parted you, spreading your slick, swollen lips wide, exposing the glistening, winking core of you to the room’s light and to Satoru's hungry stare.

"There," Satoshi murmured, his own breath coming faster, his throat bobbing, "Look at that. So wet. All for us."

From the chair, there was a choked-off groan. Satoru's fist was moving faster now, a frantic rhythm visible through the denim. His other hand gripped the back of the chair, knuckles white. "God, fuck," he panted. "Hurry the fuck up. Make her cum."

Satoshi grunted, a sound of strained patience, scowling at his brother. "I told you. Be patient. She's not going anywhere." But his own control was fraying. You could feel the tremble in the arms wrapped around you, the ragged puff of his breath against your neck.

He kept you spread open for another long, excruciating moment, letting Satoru, and you, see everything. Then, finally, one of his thumbs left its post. It trailed downward, through your drenched folds, gathering slickness, before circling your clit with a firm, knowing pressure.

A broken cry tore from your throat. Your head fell back against Satoshi's shoulder, your eyes squeezing shut as pleasure, sharp and electric, jolted through you.

"Eyes open, baby," Satoshi ordered, his voice rough, "Look at him. Watch him watch you come apart."

Forcing your eyes open was a Herculean effort. Through a haze of lust, you met Satoru's gaze. He was staring, transfixed, at the place where his brother's thumb worked you over. His own hand was a blur now, his hips pumping slightly into his fist. He looked utterly wrecked, a mirror of your own unraveling, white hair mussed as he sunk a fang down on his lower lip, muffling his moans.

"That's it," Satoru urged, his voice a hoarse whisper, "Just like that. Fuck, look at her. C'mon, 'Toshi, give her more."

Satoshi, done waiting, done teasing, finally sank one long, clever digit deep inside you. A perfect invasion, as Satoshi's finger, long and dexterous, the one of a theorist who solved complex equations in his head, slid into your sopping heat with no resistance, burying itself to the knuckle in one smooth, devastating stroke. A wet, obscene squelch filled the quiet room, louder than any moan.

"Fuck," you sobbed, your body bowing against his chest, back arching as your tits pushed out.

Satoshi didn't pause. He began to move, a slow, deep, piston-like rhythm that was ruthlessly efficient. His other thumb continued its relentless circles on your clit, the dual assault short-circuiting all coherent thought. You were reduced to sensation: the scratch of his blue cable-knit sweater against your bare back, the faint, clean scent of laundry detergent and him, the fogged lenses of his glasses as he watched his own hand disappear into you with a focused, academic intensity.

The quiet twin was conducting an experiment, and you were his glorious, messy result.

"So tight, you know I've never done this before," he murmured, his voice a low rasp against your ear, "And so deep. You're taking me so well."

He crooked his finger, searching, and found that spot that made you see stars. You shrieked, your nails digging into the thick thighs bracketing you.

From his chair, Satoru let out a guttural sound. The rhythmic motion of his fist under his jeans had become frantic, desperate. He was leaning forward now, elbows on his knees, his gaze fever-bright and fixed on the junction of your bodies, on his brother's wrist moving in and out of your glistening cunt.

"God, you're so wet, I can see it from here," Satoru gasped, his voice strained. He ran a hand through his artfully messy white hair, leaving it standing on end. The thin gold chain around his neck glinted under the desk lamp. The tight white tee stretched across the defined planes of his chest and shoulders, damp with a light sweat, "Fuck, sweetheart. I’m gonna…Can I? Can I come on you?"

The request was raw, filthy, stripped of all your best friend's usual bravado. It was pure, unadulterated need.

You couldn't form words. You just nodded frantically, a desperate, pleading moan ripping from your throat as Satoshi added a second finger, stretching you exquisitely, the wet sounds growing louder, more vulgar.

"She says yes," Satoshi interpreted, his own breath coming in harsh pants. He was losing his clinical composure, his thrusts becoming harder, faster, "Do it. Mark her."

With a ragged shout that was half curse, half prayer, Satoru shoved his jeans down over his hips just enough. His cock sprang free, thick and flushed and already leaking. His fist flew over his length, his eyes locked on your face, then dropping to your tits, which were jiggling with every one of Satoshi’s deep drives.

"On your tits," Satoru groaned, the words slurred with pleasure. "Gonna' paint those perfect tits, sweetheart. Fuck, fuck —!"

His climax hit him like a train. Satoru's body tensed, a corded muscle sculpture in the lamplight, and with a final, choked cry, thick, hot ropes of cum shot across the space between you. They landed on your stomach, your heaving breasts, striping your skin with pearlescent streaks. One particularly forceful jet hit your nipple, and the sensation, the shocking heat, the sheer taboo of it, made you convulse around Satoshi's fingers, earning a hiss from the other twin.

Satoru slumped back in the chair, breathing like he'd just finished a sprint, a dazed, satiated grin spreading across his face, "Holy shit," he panted, two flushed rounds of colour painted over his handsome features.

Before you could even process the new, sticky warmth on your skin, Satoru was moving again. He surged up from the chair, his jeans still around his thighs, and closed the distance between you in two strides. He didn't hesitate. One hand, still slightly sticky, cupped your cheek. The other braced on the headboard behind you.

Then he kissed you.

It was nothing like Satoshi’s intense, clumsy initial kisses. This was all Satoru. Confident, demanding, flavoured with cheap beer and victory, and a hint of some sweet candy he was always carrying around in his pocket.

His tongue plunged into your mouth, claiming it with the same easy arrogance he claimed everything else. You could taste his sweat, his exhilaration. The thin gold chain brushed cold against your collarbone. Your senses were overwhelmed, Satoshi's fingers fucking you deep, Satoru's tongue in your mouth, the smell of sex and Oreos and cologne in the air.

"Knew you'd be this fucking hot," Satoru mumbled against your lips between searing kisses, "Knew it. God, look at you. Taking my brother's fingers like a champ. Wearing my load."

His words, the possessive feel of both twins on you and in you, tipped you over the edge. The coil in your belly, wound impossibly tight by Satoshi's expert, relentless attention, finally snapped.

A sound tore from you that was neither a scream nor a moan but something primal, something that started in your toes and erupted from your throat. Your back arched violently off Satoshi's chest. Your inner walls clamped down on his buried fingers in a series of frantic, fluttering pulses. And then, with a gushing, uncontrollable rush, you squirted.

Hot liquid soaked Satoshi's hand, his wrist, the bedspread beneath you. It wasn't a trickle; it was a release, a soaking wave of pleasure that left you trembling and boneless. Satoshi groaned, a deep, shattered sound, and pressed his face into your neck, his fingers still working you gently through the aftershocks, milking every last drop.

Satoru broke the kiss, pulling back to watch, his blue eyes wide with awe and a fresh, rekindled hunger, "No fuckin' way," he breathed, a laugh of pure disbelief bubbling out of him. "You are full of surprises, sweetheart."

And for a long, breathless moment, the only sounds were the ragged symphony of your breathing and the wet, soft sound of Satoshi's fingers slowly sliding out of your spent cunt.

Then the spell broke.

"My turn," Satoru announced, his voice still rough but regaining its characteristic swagger. He wiped his hand on his thigh, his gaze fixed on you with a possessive heat that made your oversensitive nerves twitch back to life, "Come on. That's my best friend right there. I think I can handle my girl."

Satoshi's arms tightened around you, a low growl vibrating against your back, a hint of brotherly annoyance colouring his voice, "What? Don't be an idiot. I kissed her first, and I can fuck that pretty pussy way better than you can."

"Bullshit," Satoru shot back, a competitive grin spreading across his face. He took a step closer, his discarded jeans now pooled around his ankles, his cock already half-hard again and glistening, "You can calculate the density of a neutron star and all that shit, bro. I know how to make a woman scream."

"Your empirical evidence is based on wasted sorority girls who can’t tell the difference between enthusiasm and skill."

"Oh, fuck you– "

"That's the general idea, but not for you."

They were glaring at each other over your shoulder, a lifetime of sibling rivalry igniting in the most absurd, heated context imaginable. You, slick and trembling and pinned between them, felt a hysterical laugh bubble in your throat. It came out as a weak, overwhelmed whimper.

The sound snapped their attention back to you. Two pairs of identical, blazing blue eyes locked onto your face.

Satoru's expression softened, just a fraction. He reached out, his thumb, sticky with his own drying release, brushing over your swollen lower lip, "Hey. You okay? You're shaking."

Satoshi nuzzled into your hair, his voice dropping to that intimate rumble, "Tell us what you want. Just say the word and he leaves. Or I'll leave."

The offer hung in the air. You could have either of them. The wild, glorious sun or the deep, consuming moon. The choice was yours.

Your body, however, had already decided. The empty, aching throb between your legs wasn't asking for one. It was screaming for more, so much more.

"Both," you whispered, the word barely audible.

Satoru's eyebrows shot up. Satoshi went very still behind you.

"What was that, sweetheart?" Satoru asked, shaking his soft, white head of hair.

You swallowed, finding your voice. It came out stronger, laced with a need that shocked even you, "Both. I want…I want both of you."

A slow, eager smile spread across Satoru's handsome face, a mirror of the dawning and intense spark in Satoshi's eyes. The previous rivalry melted, replaced by a unified and predatory focus.

"Okay, okay," Satoru breathed, like he'd just been handed the winning play, "Fine. Both it is."

He moved with practiced ease, stepping out of his jeans completely. He sat back on the edge of Satoshi's bed, scooting until his back was against the headboard. The Star Wars poster loomed behind his head like a benediction. He patted his thighs, "Up here. Straddle me. Let me see you sittin' all pretty on me, yeah?"

You clumsily extricated yourself from Satoshi's embrace. His hands lingered on your hips, guiding you as you turned and climbed onto the bed, your knees sinking into the mattress on either side of Satoru's hips. The movement smeared the mess of cum and squirt already on your skin. Satoru's gaze dropped, watching the slick shine between your thighs with avid hunger.

He reached out and gave your ass a sharp, stinging slap. The sound cracked in the quiet room. You yelped, more from surprise than pain, and fresh wetness trickled down your inner thigh.

"Look at that," Satoru murmured, his hand smoothing over the reddening print, messily spreading the fluids, "Fucking perfect." Then his eyes lifted to yours, and the bravado flickered, revealing a sliver of genuine concern, "Is this okay, sweetheart? This…all of this? Is this alright?"

The question, so tender amidst the filth, undid you. You nodded frantically, leaning forward to kiss him, tasting yourself and him on his lips, "Yes," you gasped against his mouth, "Yes, I want more. Please."

"Good girl," he growled, his mouth slanting against yours, hard, tongue sliding through your parted lips.

From behind you, there was the distinct, crinkling tear of foil. You glanced over your shoulder. Satoshi stood beside the bed, having retrieved a condom from somewhere, his desk drawer, perhaps. He was rolling it down his length with meticulous care, his glasses perched on his nose, his blue sweater still on, making him look like a debauched professor. His eyes met yours, dark with promise. And still, there was that adorable flush on his cheeks, pink watercolour over cream.

Satoru, meanwhile, fumbled in the pocket of his discarded jeans, which were tangled on the floor. He pulled out not one, but two foil squares, flashing you a triumphant grin, "Always prepared," as he ducked your playful swat. He sheathed himself quickly, his movements impatient.

He gripped your hips, his fingers digging in. "Ready?" he asked, his voice thick. You nodded, bracing your hands on his shoulders. You felt the broad, blunt head of his cock nudge against your soaked entrance.

Satoru didn't make you do the work. With a grunt, he lifted his hips and pulled you down at the same time, sheathing himself inside you in one deep, relentless thrust.

"Fuck!" you cried out, the stretch exquisite, familiar yet new. He filled you completely, the angle different from Satoshi's fingers, claiming you in a way that felt fundamentally Satoru. Immediate, overwhelming, and gloriously intense.

"God, you're tight, and so fuckin' wet," he groaned, his head falling back against the headboard, "So fucking good. Okay, 'Toshi. Your turn. Be gentle with our girl."

You felt Satoshi's weight dip the mattress behind you. His hands, cool and sure, spread your ass cheeks. There was a pause, the press of something much larger and blunter than a finger against your other, untouched hole, slickened by the mixed fluids smeared there.

"Breathe out, baby," Satoshi instructed softly, his voice the calm in the storm, "And relax."

You exhaled, forcing your muscles to unclench. He pushed forward, slow, inexorable, a burning, stretching pressure that stole the air from your lungs. It hurt, a sharp, bright sting, before melting into a deep, impossible fullness as he seated himself fully inside you.

You were split open, impaled on both twins, stuffed so completely you couldn’t tell where one ended and the other began. A choked, guttural sound was torn from your throat, a noise of pure, overwhelmed sensation.

Satoru's eyes were wide, his mouth agape as he felt Satoshi's intrusion through the thin barrier of your shared walls, "Holy shit," he rasped. "I can feel you. I can feel him."

Satoshi grimaced, "Don't say that shit, man," But he let out a shaky, shattered breath, his forehead dropping between your shoulder blades. "Move," he gritted out, "Or I will."

Satoru, never one to back down from a challenge, obeyed. He rocked his hips upward, and the world dissolved into a cascade of blinding, contradictory sensation, the drag and fill of Satoru in your pussy, the burning, stretching fullness of Satoshi in your ass. They set a rhythm, hesitant at first, then faster, deeper, finding a syncopated pace that drove you up the bed with every thrust.

Satoru's gold chain swung and slapped against your chest with each drive. Satoshi's sweater scratched your back, his quiet grunts hot in your ear. The bed, Satoshi's perfectly ordered bed, slammed against the wall with a rhythmic, protesting thump-thump-thump! that matched the pounding of your heart.

The rhythm was brutal, perfect, and utterly consuming. Satoru's thrusts were powerful, athletic drives that punched the air from your lungs, while Satoshi's were deeper, slower, more deliberate, each one a calculated invasion that stretched you to a breathtaking limit. You were the fulcrum between them, a trembling bridge of pleasured flesh and sensation.

"Fuck, she's so tight like this, bro," Satoru grunted, his hands vice-like on your hips, guiding your bounces on his cock. Sweat gleamed on his temples, dampening the white hair at his forehead. His gold chain swung wildly, catching the light with every snap of his hips, "Can you feel him? Can you feel me hitting right against him?"

You could. The pressure was immense, a dual fullness that bordered on delicious pain before tipping over into mindless pleasure with every synchronised push. A garbled, affirmative sob was all you could manage, "Yes, yes! Ah - I can feel you both! Don't stop!"

Satoshi groaned behind you, his voice a strained rasp against the shell of your ear, "Yeah, you like when we've got you pinned up like this? Fuckin' nasty girl, been wanting this forever," He shifted his angle slightly, and the head of his cock dragged over a spot inside you that made stars burst behind your eyelids.

"Ohh! Satoshi!"

"There?" The quieter of the brothers murmured, doing it again, a precise, devastating rub, "Good."

"Hey, quit hogging the good spots, bro," Satoru complained, but his grin was feral. He leaned up, capturing your mouth in a sloppy, breath-stealing kiss. You could taste the beer on his tongue, the salt of his sweat. "She's mine too. Aren't you, sweetheart? My best fucking friend." He punctuated the claim with a particularly deep thrust that made you break the kiss with a cry.

"Yours," you gasped, as his cock kissed the sweet spot in your wet, pulsing cunt, the word fracturing. "Both, yours – "

"Damn right," Satoru growled, his composure fraying. His pace became erratic, frantic, "Gonna' fill this cunt for you. Gonna' mark you up inside. 'Toshi, you close?"

Behind you, Satoshi’s breathing was ragged, his usual quiet control shattered. His thrusts lost their mathematical precision, becoming just as hungry, just as desperate. The rough wool of his sweater was soaked through with sweat where your back pressed against him, "Yeah, I'm e-exceedingly close," he managed, his voice thick, "Her body is...incredibly receptive."

"Yeah, no shit, fuckin' nerd," Satoru complained, but there was no real animosity behind the shattered laugh, the sound breathless, "Come on, sweet girl. Come with us. Let go. Soak our cocks real good."

The command, the overwhelming sensation of being claimed and used and cherished by both of them, broke the last dam. Your third orgasm tore through you, silent at first, a full-body seizure, your internal muscles clamping down in violent, fluttering spasms around both invading lengths, before a raw, broken scream was ripped from your throat.

That was all it took.

Satoru shouted, a loud, uninhibited roar, his hips stuttering as he buried himself to the hilt and held there, pulsing hotly into the condom deep inside you. The feeling of him coming triggered his twin, who let out a choked, guttural sound that was nothing like his usual voice. Satoshi pressed his face into your neck, his body going rigid as he emptied himself with a series of sharp, shallow thrusts.

For a long moment, there was only the sound of three bodies gasping for air, the room hazy with sex and sweat and spent passion. And then, the inevitable collapse.

Satoru's arms gave out first. He slumped back against the headboard, his grip on your hips loosening. Satoshi, with a final, shuddering exhale, carefully pulled out of you. The sudden emptiness was a shock, a cool void where there had been overwhelming heat. You simply folded forward, boneless, sinking into the soft, now thoroughly wrecked sheets of Satoshi’s bed. You were aware of sticky dampness everywhere, the ache of deep, pleasurable and thorough use, and a floating, satiated exhaustion that weighed down your very bones.

The silence stretched, comfortable and heavy. It was broken by Satoshi clearing his throat. He had already disposed of his condom and was pulling his sweater back into some semblance of order, though his hair was a disaster and his glasses were still fogged, slipping down his nose.

"Alright," he said, his voice returning to its normal, dry timbre. He nudged Satoru's leg with his foot. "Out. Go clean yourself up. This is my room."

Satoru, who had been lying with his eyes closed, a blissed-out smile on his face, cracked one eye open. "Wow. Let a guy fuck his girl, and toss him out. Classy."

"You have your own room. With your own mess. This – ," Satoshi gestured vaguely at the climax-striped sheets, the overturned plate of Oreo crumbs now scattered on the floor, the general aura of debauchery, your top still sprawled over the floor, " – is my mess. I'll deal with it. Go."

With a long, dramatic sigh that was entirely performative, Satoru sat up. He dealt with his own condom, then reached for his jeans, hopping on one foot as he tugged them on. He didn't bother with the boxers still somewhere on the floor, ignoring Satoshi's disgusted scowl. "Fine, fine. The walk of shame. This is a new low." He shot you a wink as he fastened his jeans, "Worth it, though."

He leaned over the bed, brushing a sweaty strand of hair from your forehead, "You're a legend, sweetheart. Get some rest." Satoru dropped a quick, surprisingly soft kiss on your temple, a flicker of something raw and unguarded loaded with the history of companionship that his brother lacked with you, before straightening up.

With a final smirk at his brother, Satoru sauntered out of the room, closing the door quietly behind him.

The quiet settled back in, deeper now. You felt the mattress dip as Satoshi lay down beside you. He didn't pull you to him immediately. Instead, he just looked at you, his gaze thoughtful behind his cleaned glasses. Then he leaned in and pressed a lingering kiss to the side of your neck, right over a mark you were sure he'd left earlier.

"He'll be back,” Satoshi sighed, his lips moving against your skin, tracing sweet patterns with his tongue, glasses nudging against your shoulder. His arm slid under you, drawing you gently against his side. The cable-knit sweater was scratchy, but his body was warm. "Probably with food. Or more beer. No doubt."
